<em>系统:Windows 7Qt版本:4.8.5Qt Creator版本:2.8.0  安装路径:Qt -> D:/Qt4.8.5Qt Creator -> D:/Qtcreator-2.8.0mingw -> D:/mingw</em> 1.配置环境变量:到“我的电脑->属性->高级->环境变量->系统变量”中编辑Path,添加:我电脑的安装路 ;D:/Qt4.8.5/bin;D:/Qtcreator-2.8.0/bin;D:/mingw/bin确定;为了让环境变量生效,如果配置环境变量之前已经打开cmd,要重新打开一个新的cmd窗口。 2.下载mysql官网www.mysql.com下载,非安装包的文件名称类似这种格式:mysql-5.5.29-win32.zip只需要mysql里面的lib和include,解压到D:/ 3.下载mingw-utils-0.3.tar.gz解压出来,将bin文件夹里面的reimp.exe拷贝到D:/Qt/qtcreator-2.4.1/mingw/bin目录,不拷贝也行,调用reimp手动添加绝对路径。 4.编译驱动打开cmd,执行以下命令:(1)转换libmysql格式cd d:/mysql/libreimp -d libmysql.libdlltool -k -d libmysql.def -l libmysql.a(2)编译qt的mysql驱动cd d:/Qt4.8.0/src/plugins/sqldrivers/mysqlqmake "CONFIG+=release" -o Makefile "INCLUDEPATH+=d:/mysql/include" "LIBS+=d:/mysql/lib/libmysql.a" mysql.promingw32-makeqmake "CONFIG+=debug" -o Makefile "INCLUDEPATH+=d:/mysql/include" "LIBS+=d:/mysql/lib/libmysql.a" mysql.promingw32-make 5.拷贝mysql驱动编译完成后,打开D:/Qt4.8.0/src/plugins/sqldrivers/mysql目录,可以看到release和debug目录,分别从release和debug目录中拷贝以下4个文件到D:/Qt4.8.0/plugins/sqldrivers:qsqlmysql4.dlllibqsqlmysql4.aqsqlmysqld4.dlllibqsqlmysqld4.a 6.拷贝mysql动态库(重要)(1)本机运行拷贝D:/mysql/lib/libmysql.dll文件到D:/Qt4.8.0/bin (2)发布应用程序没有mysql的电脑,若要发布应用程序,要跟着libmysql.dll一块发布,与应用程序同级目录。 7.测试mysql可用性加入已经存在mysql服务,那么编写以下代码测试:(1).测试是否有驱动QStringList driverList = QSqlDatabase::drivers();  qDebug()
